Biomechanics of the Foot
- Heel-strike
- IR tibia, calcaneal eversion, unlocking TN + CC joints = foot pronation to decelerate impact of weightbearing
- Foot-flat
- weightbearing axis through ASIS → patella → 2nd MT
- Toe-off
- ER tibia, calcaneus inverts, transverse tarsal joints locked (via pull tibialis posterior tendon) = rigid lever for gait
- Flatfoot deformity
- ↑stress on ligaments. Abducted everted foot can lead to tibialis anterior + Achilles tendons acting as evertors
